In your search of the forum did you see the correction for most P0410 problems is corrected by replacing worn contacts on the Relay Control Module (RCM)? One of our members provides us great service by refurbishing your RCM for like $30. It is a fast turn around and saves you a good bite of money.
You can do more research just by placing P0410 in the search box. If you are still running the original RCM then it would be wise to let him refurbish it for you. email: tighed1@hotmail.com for his help.
